DigiDop 300 OB Doppler


Newman Medical Model DD-300 Non-display Digital Fetal Doppler (select one of the above probe options): display indicates battery, volume, and signal strength status - DOES NOT display heart rate

Product Details

These audio only Dopplers provide great value if all you need is to hear the Doppler sounds loud and clear. They include a display of battery condition, signal strength, and volume setting, but do not have a heart rate display.

Superior sound quality

Our Dopplers have the sensitivity and audio response to allow you to hear the fetal heart tones quickly and clearly. All our DigiDops have our state of the art Digital Sound Clarity – DSC™. A sound processor in the main unit enhances the sounds you want to hear while reducing those you don’t. The DSC™ processing is optimally set for each different probe frequency.

The DigiDops speakers are small but powerful high fidelity speakers that have extraordinarily smooth and rich response over the whole range of Doppler sounds.

Obstetrical Probes

All DigiDop obstetrical probes provide the sensitivity and reliability you need. All probes will work on all DigiDops for maximum versatility. Our 2 and 3 MHz obstetrical probes utilize our exclusive eXtended Depth – XD™ technology that has increased sensitivity at closer depths without sacrificing it at deeper depths. These probes create more than six times as much signal at some depths than other probes. All of our OB probes have a smooth contour design that is comfortable to hold, comfortable for the patient, and easy to clean.

  • 2 MHz probes provide excellent deep penetration for late term pregnancy or larger patients.
  • 3 MHz probes are especially sensitive to early fetal hearts but can also be used throughout the pregnancy.
  • Both 2 and 3 MHz probes are available in water proof versions for water-assisted labor and delivery. These waterproof probes can be removed from the DigiDop and replaced with a standard probe.
  • A variety of vascular probes may be used interchangeably with any DigiDop.

Built to last

With our industry-leading five-year warranty we have made sure that the DigiDop will stand up to hard use day after day. The combination of our sturdy design and warranty can save you significant service costs.

The body is made of a mix of tough plastics with a unique stainless steel grill over the speaker. Our latest DigiDop’s smooth, clean lines are also more comfortable in the hand. The grill now has micro-screen openings to protect the speaker; the speaker itself has an internal sound transparent fabric cover to keep out dirt and dust.

Our unique magnetic probe holder won’t crack or break and gently cradles the probe when not being used. The strong magnets we use hold the probe without being sensitive to how it’s rotated. The open design avoids gathering dirt, gel and germs.

Industry Leading Five Year Warranty

All DigiDop Doppler come with a ‘bumper-to-bumper’ 5 year warranty. The warranty includes both parts and labor and covers not just the main unit but also the probes and cords. We can offer this outstanding warranty because our design and materials reduce the number and cost of warranty issues.


The alkaline batteries provided with the DD-300 provide hours of use, enough for hundreds of typical exams.

Made in the USA

Our products are designed and manufactured near Denver Colorado, a long-time center for diagnostic ultrasound products. Each product, including each probe, is individually inspected and tested to assure quality and durability. We have a very experienced team that has been in the Doppler business for many years – back to the time the first fetal Dopplers were introduced.
